Abstract
A probe assembly is provided which includes a housing, at least one sensing element extending through a passageway in a wall of the housing and a sealing packing element mounted in the passageway for effecting a pressure-tight seal between the sensing element and passageway. The housing has a generally pipe-shaped neck portion, one end of which has disposed thereacross the housing wall through which the passageway extends, and the sensing element is at least partially disposed in the neck portion in a direction generally parallel to the longitudinal axis of the neck portion. The neck portion is filled with a heat-resistant, porous filler material, which prevents damage to the sealing packing element.
